Objective: Obsessive-compulsive disorder (OCD) is a frequent neuropsychiatric disorder, in which genetic factors play important causative roles. We investigated the roles of the (-1019 C/G) promoter region polymorphism of 5-HTR1A and the G861C coding region polymorphism of 5-HTR1B genes in susceptibility to OCD in a Turkish population.

Methods: Two single nucleotide polymorphisms, 5-HTR1A (rs6296) and 5-HTR1B (rs6295) genes were genotyped in 76 OCD patients and 57 healthy controls that were unrelated, using PCR-RFLP method.

Results: We did not observe any difference in the genotype distributions of rs6296 and rs6295 between the OCD patient and control groups.

Conclusions: As far as we know, our study is the first to establish the association of genetic variants 5-HTR1A (rs6296) and 5-HTR1B (rs6295) with OCD in a Turkish population. Based on our results, the relationship between polymorphisms of 5-HTR1A (rs6296) and 5-HTR1B (rs6295) with OCD do not seem.
